Bermad IR-430-55-R Series Metal Hydraulically Operated Pressure Sustaining/Relief Valves with S.390 Coil

The Bermad IR-430-55-R is a high-precision hydraulically operated, diaphragm-actuated control valve designed to sustain a minimum preset upstream pressure or relieve excess line pressure when installed offline. Equipped with a solenoid actuator, it integrates seamlessly with automated and remote irrigation systems, opening or closing in response to electric signals from a controller.

Ideal for pressure zone management, pump protection, and system safety, this valve ensures optimal pressure conditions throughout varying flow regimes, safeguarding both water delivery and infrastructure performance.

APPLICATIONS

• Automated and computerized irrigation networks
• Pressure zone prioritization in hilly or elevated terrain
• Pump protection and cavitation prevention
• Irrigation machines and low-supplied pressure systems
• Controlled fill-up and line emptying prevention
• Remote field plots requiring pressure stabilization
  

FEATURES

• Dual-function valve: pressure sustaining and relief
• Hydraulic control with solenoid actuation for automated systems
• Maintains upstream pressure during demand fluctuations
• Relieves excess pressure when line pressure exceeds preset limit
• Electric On/Off control with wide voltage compatibility
• Globe-pattern hydro-efficient design with high flow capacity
• Single moving part for long-term reliability
• Fully supported and balanced diaphragm for stable operation
• Excellent low-flow regulation and progressive closing action
• In-line serviceable for simple maintenance and pressure adjustment
• Durable construction designed for harsh irrigation environments
  

INSTALLATION

• Ensure clear access around the valve for service
• Install isolation valves upstream and downstream
• Flush the pipeline prior to valve installation
• Match flow direction with arrow on valve body
• Best installed horizontally and upright for stability
• Verify solenoid voltage matches system design
• Use approved cable protection and proper wiring specifications
• Warning: Never energize the coil unless properly mounted—risk of coil damage
